The delay is due to the complex rules introduced in the Paris agreement to deal with the possibility that a future US president will decide to withdraw the country from the agreement. Taking part in an election campaign promise, Trump – a climate denier who has claimed that climate change is a “hoax” perpetrated by China, announced in June 2017 his intention to withdraw the United States from the Paris Agreement. But despite the rose garden president`s statement that “we`re going out,” it`s not that simple. The withdrawal procedure requires that the agreement be in effect for three years before a country can formally announce its intention to withdraw. She`ll have to wait a year before she leaves the pact. This means that the United States could formally withdraw on November 4, 2020, the day after the presidential elections. Even a formal withdrawal would not necessarily be permanent, experts say. a future president could join us in a month. The authors of the agreement have set a withdrawal period that President Trump must follow – which prevents him from irreparably harming our climate. “The decision to leave the Paris agreement was wrong when it was announced, and it`s still wrong today,” said Helen Mountford of the World Resources Institute.
The same nations that are asking us to maintain the agreement are the countries that have cost the United States billions of dollars through hard trade practices and, in many cases, lax contributions to our critical military alliance. You see what`s going on. It`s pretty obvious to those who want to keep an open mind. It is rare that there is a consensus among almost all nations on a single subject. But with the Paris agreement, world leaders agreed that climate change was driven by human behaviour, that it was a threat to the environment and to humanity as a whole, and that global action was needed to stop it. In addition, a clear framework has been put in place for all countries to make commitments to reduce emissions and strengthen these measures over time. Here are some important reasons why the agreement is so important: it will also allow the contracting parties to gradually increase their contribution to the fight against climate change in order to achieve the long-term objectives of the agreement. President Trump is pulling us out of the Paris climate agreement. “This is certainly a blow to the Paris agreement,” said Carlos Fuller of Belize, the negotiator for the Alliance of Small Island States in the UN talks. The Paris Agreement has an “upward” structure unlike most international environmental treaties, which are “top down”, characterized by internationally defined standards and objectives that states must implement.  Unlike its predecessor, the Kyoto Protocol, which sets legal commitment targets, the Paris Agreement, which focuses on consensual training, allows for voluntary and national objectives.
 Specific climate targets are therefore politically promoted and not legally binding.
